About Me

experienced | passionate | international


My journey

My journey started in Germany. I studied law and worked as In-house counsel for a bank. After migrating to Australia, I qualified as a Barrister.

In 2002, I completed my post-graduate studies in international commercial and sports arbitration and developed an interest in digital dispute resolution. In the same year, I also became a member of the Chartered Institute of Arbitrators (CIArb).

Soon after, I debuted as a mediation co-counsel for the State of Queensland and began advising parties, counsels and State and Federal governments in national, regional and international mediation, arbitration, and litigation matters.

In 2014, I took the position as Principal Lawyer and Attaché to the Secretary General of the Hague Conference on Private International Law (HCCH). I worked on the HCCH’s international commercial and financial law and civil procedure instruments. I also advised the Secretary General on the laws of international organisations.


Since 2020, I work as an independent and accredited mediator and arbitrator. My practice is as diverse and international as is my expertise.

Being a national of Australia and Germany, I am fully proficient in English and German and practice in both languages.

I undertook extensive online dispute resolution (ODR) training and am very skilled in conducting mediations and arbitrations online.

My expertise is well recognised. I am a member of several leading international mediation and arbitration panels.

Moreover, I lecture at graduate and master’s level, including courses in mediation, at the  Sigmund Freud University in Vienna and I take pride in coaching mediation and arbitration teams at moot competitions. Since 2023, I am the Director of the IBA-VIAC CDRC Mediation & Negotiation Competition, the world’s most prestigious mediation competition.

I am a much-published author and regular speaker at webinars, seminars and conferences, always  happy to share my experience and insights.
